A mechanical keyboard uses a physical switch under a keyboard. This switch determines when the user presses a button. Having mechanical parts, mechanical keyboards are also more prone to damage compared to membrane keyboards. 

Whether the reasons are dust and debris, physical damage, or a faulty switch, mechanical keyboard’s keys not working is one of the common problems for most users. 

This article discusses a few methods you can follow to repair your keys on a mechanical keyboard.

Why Are Keys on My Mechanical Keyboard Not Working?

Dust and debris may enter the key switches, especially if you snack near your mechanical keyboard. Once enough dust enters your keyboard, it can stop a key from hitting its switch while you press on it. Also, a worn-out cable or a damaged key switch is known to stop mechanical keys from functioning.

Here are a few reasons the keys on your mechanical keyboard do not work.
  • Dust and debris
  • Faulty key switches
  • Worn out cable
  • A dead battery
  • Outdated drivers or the Operating System
  • OS using a different keyboard layout
  • Filter keys are on

Mechanical Keyboard Key Not Working? Here’s How to Fix It

When a keyboard does not work, it’s either a hardware issue or an issue with internal OS components. Let’s go through both of them briefly to get your keyboard working again.

Clean the Keyboard

Any keyboard, if left uncleaned, will collect dust over time. On a mechanical keyboard, this dust may stop the switches from being pressed. Cleaning the keyboard should fix the issue with a faulty key.

To clean a mechanical keyboard, you can either use a can of compressed air or remove the keys altogether to clean them thoroughly. If you are using compressed air, make sure that you use it carefully since the keys will fall off the keyboard pretty easily. 

In order to remove the keys use a keycap puller. Gently remove the keys and use compressed air to clean dust from the areas you can’t reach. Using 99% isopropyl alcohol is also a viable option to clean your keyboard. 

While cleaning the keyboard make sure that the keyboard is not connected to a power source.

Change Batteries on Wireless Keyboard

In case you are using a wireless mechanical keyboard, OS may not detect a keypress from your keyboard if its batteries are down. Try changing the batteries on your keyboard to see if it fixes the issue. If it is a rechargeable keyboard, connect it to a charger.

Batteries on your rechargeable keyboard may also get damaged. If this happens, the keyboard will work as long as your charger is connected to the keyboard. However, once you remove the charger, its battery will no longer function and the keypress does not get registered.

You need to replace your batteries in such a scenario as well.

Replace the Cable

A mechanical Keyboard can also come with a detachable USB C cable. A damaged cord may also stop some of its functionalities, such as keypress not detecting. If you see any part of the cable worn out, maybe that’s what’s preventing the keypress from detecting.

Replace the worn-out cable with a new one to see if it fixes the issue.

Replace Switch

Removing Keycaps in a mechanical keyboard

As mentioned earlier, when you press a key on a mechanical keyboard, it hits a switch that sends a signal to the OS. If this switch is faulty internally or is damaged, the system will not detect anything. And if none of the above solutions work, there is a high possibility that the switch itself is damaged.

Using a switch puller, you can easily remove and replace keys if your keyboard has a hot-swappable switch. However, if you do not have hot-swappable switches, you may need to do some soldering to replace the switches.

Using a solder to replace switches can be difficult. Therefore, we recommend taking the keyboard to a local electronic shop to replace the keyboard switch.

Enable On-screen Keyboard

If none of the solutions work, you can use an on-screen keyboard as a temporary fix. An on-screen keyboard uses mouse clicks to register the keypress. 

Follow the steps mentioned below to enable the On-Screen keyboard.

  1. Click on the Windows icon on the taskbar.
  2. Click on All Apps and select Settings.
  3. Go to Accessibility > Keyboard.
  4. Under On-screen keyboard, access keys, and Print screen, enable On-screen keyboard.
    enable on screen keyboard

Note: Some of the following settings mentioned below require keyboard shortcuts. Enable on-screen keyboard to perform those solutions.

Change Keyboard Layout

Depending on the keyboard layout you use, some keys will not function as desired. For example, if the layout is set to English (UK), pressing Shift + 2 will display the * symbol instead of @ symbol. 

If you are using a different keyboard layout, pressing a key may cause confusion that a keypress is not working. 

Press the Windows + Space key or Alt + Shift key to switch between different keyboard layouts.

If the keys are not working, follow the steps mentioned below.

  1. Search for the system tray icons on the taskbar. It is usually located on the right side of the taskbar. Click on the currently displayed language.
  2. Now change the layout by selecting a different language.
    change keyboard layout

Follow the steps below if you want to remove any unnecessary keyboard layout.

  1. Click on the Windows icon.
  2. Click on All Apps, then select Settings.
  3. Go to Time & language > Language & region.
  4. Under Language, you can see all the installed languages. 
  5. Click on the three horizontal dots and select Remove.
    remove keyboard layout

Turn Off Filter Keys

Enabling filter keys will ignore multiple simultaneous key presses. This particular setting can be beneficial for people with hand tremors to avoid random keyboard input. However, enabling this setting may seem like the keys on your keyboard are not working. 

Follow the steps mentioned below to disable filter keys.

  1. Click on the Windows icon on the taskbar.
  2. Click on All Apps, scroll down and select Settings.
  3. Go to Accessibility > Keyboard.
  4. Under Stickly, Filter, and Toggle keys, disable Filter keys. 
    Turn off filter keys windows 11

Run Keyboard Troubleshooter

The troubleshooter feature in Windows lets you find and fix problems with malfunctioning hardware. Using this tool, you can even fix any issues that may stop a keyboard key from functioning.

  1. Click on the Windows icon on the taskbar.
  2. Click on All Apps and select Settings.
  3. Go to System > Troubleshoot > Other troubleshooters.
  4. Under Other, run the Keyboard troubleshooter.
    Windows 11 keyboard troubleshoot run
  5. Once the troubleshooter process completes, restart your computer to see if the keys work
